Code That Made Me Cry, #CTMMC™

95% of all code makes me cry. The other 5% are white space.

Operator Overloading (Scala, #32 / 50)

(children :\ 0) (_.size + _)

// is equivalent to
children.foldRight(0)(_.size + _)

// and is also equivalent to
children.foldRight(0)((a,b) => a.size + b)

After our collective minds have finally gotten rid of C++ and Perl, here come the Scala guys and treat us to beautifully cryptic operators all over the place. Because really, the new 'paid by the number of lines of code' is 'paid by the number of special characters

(We know, it's not overloading, it's symbolic method names. It reads just the same)
